Benefits of technology

"The present invention proposes a solution to the problems of previous compressor structures that used conventional check valves. Instead, flow control passages are used to control flow and avoid mechanical moving elements that can cause issues. This is achieved by configuring specific flow passages that direct fluid flow to achieve the desired function. The technical effect of this invention is to improve the performance and reliability of compressor structures."

Problems solved by technology

Such check valves, while long used in such applications and well known, have known mechanical failures, including sticking or becoming unseated, which impair or prevent compressor operation.

Abstract

The problems of prior compressor structures relying upon conventional check valves are obviated by using, instead, flow control passages which operate to control flow while avoiding mechanical moving elements which may become problematical.

Description

FIELD AND BACKGROUND OF INVENTION[0001]This invention relates to flow control in a compressor and more particularly to arrangements which obviate the need for more conventional check valves.[0002]The has been a proposal to use a trilobal impeller or rotor within a quadrilateral housing to move a fluid, such as a refrigerant fluid, from a region of low pressure to a region of higher pressure, in a manner consistent with the operation or prior art compressors. In such devices, conventional check valves, formed with spring loaded balls seated on seats, have been used to control flow through the compressor. Such check valves, while long used in such applications and well known, have known mechanical failures, including sticking or becoming unseated, which impair or prevent compressor operation.SUMMARY OF THE INVENTION[0003]The present invention contemplates that the problems of prior compressor structures relying upon conventional check valves may be obviated by using, instead, flow con...
